delete_line_from_file

delete_line_from_file($file,$line,$timeout=COMMAND_TIME); - delete the specified line in the file, available from version 7.0.4

The function accepts parameters as input:

$file – path to the file to delete the line in. It can be either absolute or relative (relative to the script folder).

$line – the number of the line to delete in the file (starts with 0)

$timeout – the maximum time to perform this operation (in seconds), by default - 60 seconds, if the operation is not completed during this time, the script continues to run further.

After testing, the function returns the result of its work to the script :

true – operation completed (boolean)

false – operation failed (boolean)

PHP example:

  textfile->".basename(__FILE__)." ";

//prepare files
$path = "test \ test_delete.txt";
$file_os->delete($path);
$file_os->copy("test \ test_dedupe.txt", $path);

//1
echo("1.Get the number of lines in the file:");
echo $textfile->get_lines_count($path)." n";
 
//2
echo("2.Remove line from file:");
echo $textfile->delete_line_from_file($path, 2)." n";

//3
echo("3.Get the number of lines in the file:");
echo $textfile->get_lines_count($path)." n";

//end
echo "
 
";

//Quit
$app->quit();
?>

Python example:

# Additional paths
import sys
sys.path.insert(0, '../../../Templates PY/')

xhe_host = "127.0.0.1:7016"
from xweb_human_emulator import *

# Start
echo("
  textfile.xxxxxxxxx  ")

# prepare files
path = "test \ test_delete.txt";
file_os.delete(path);
file_os.copy("test \ test_dedupe.txt", path);

# 1
echo("1.Get the number of lines in the file:");
echo(textfile.get_lines_count(path), "
");

# 2
echo("2.Remove line from file:");
echo(textfile.delete_line_from_file(path, 2), "
");

# 3
echo("3.Get the number of lines in the file:");
echo(textfile.get_lines_count(path), "
");

# end
echo("
